a few months ago my dad who at 80 had always been fit, healthy and active suddenly started to experience breathing difficulties and was diagnosed with an asbestos related cancer mesothelioma . He is now the shadow of a man I knew. He is old and weak and it breaks our hearts to see his health diminishing daily. Yesterday whilst out he suffered severe sickness and diarrhoea. I can't understand if these are signs of his final days. On liquid morphine now as pain is so bad. He has been told the prognosis but will not discuss it with us. Any clues anyone?
